Do any of you get too concerned about the color in the soap being intense enough to slightly color the washcloth (washes out) but the bubbles are still white. Seems like if I color enough to get the bold bright look I'm going for then it will make the washcloth a little colored. Does this usually happen or are there colors out there that absolutely do not do this? I have always been a little conservative with coloring my soap but would like to branch out a little more with the color thing.
